Itis obvious,npon examiningthe drawing, that flame I could not becommunicatdfrorn the wick-tube 0 providing a receptacle or.-

thronghthe packing of cotton D to the oil in the globe, B, and it is equally obvious that sodong as the globe is kept even half full of oil that a sutficiency thereof for combustion'will be forced up through the cotton D and carried up by the aid of capillary attraction to the npperend of the wick-tube.
